GridLOCK’s Policy on Harassment

GridLOCK seeks to create a safe, fan-created, equality driven space for all participants to celebrate Sherlock Holmes and Sherlock Holmes-related media. It is the policy of GridLOCK that no member of the GridLOCK community – including but not limited to attendee, staff member or volunteer – may harass any other member of the community.

GridLOCK is dedicated to providing a harassment-free convention experience for everyone, regardless of gender, gender identity and expression, sexual orientation, disability, physical appearance, body size, race, age or religion. We do not tolerate harassment of, prejudice towards, or violence against convention participants in any form.

Harassment is any unwelcome conduct of a physical, verbal, sexual nature, which includes, but is not limited to: unwelcome sexual advances; conduct that creates a hostile, intimidating or offensive environment; inappropriate touching or kissing; conduct that has the effect of unreasonably interfering with an individual’s enjoyment of the convention; unnecessary references to parts of the body; offensive verbal comments related to, but not limited to, the above mentioned groups; deliberate intimidation; stalking; harassing photography or recording; sustained disruption of discussions, panels, or other events; inappropriate physical contact; unwelcome sexual attention; other verbal, nonverbal, or physical conduct that limit a person’s ability to participate in or enjoy programming.

Costume play (“Cosplay”) is not consent. You may not touch a cosplayer, their costume, their props, or their property without their explicit consent. Please ask for consent before taking photographs of cosplayers or anyone else, and please respect people’s wishes with respect to photography and recording.

Participants asked to stop any harassing behavior are expected to comply immediately. Conference organizers may take any action they deem appropriate against convention participants violating these rules. This includes, but is not limited to: warning the offender, expulsion from the conference with no refund, expulsion from further GridLOCK sponsored events.  This policy applies to all participants, including members, speakers, vendors, and hotel staff and extends to harassment in person as well as on social media (including but not limited to Twitter, Tumblr, and Facebook).

All members of the convention community are responsible for creating safe, equal, and enjoyable environment that is free of discrimination and harassment. It is important to contact a staff member, volunteer, or another appropriate authority if any of the following occurs:

  • You believe you have been subjected to conduct or comments that may violate these policies;
  • You believe you have been retaliated against in violation of these policies; or
  • You have been told about or witnessed conduct that may violate these policies.

Conference staff will be happy to help participants contact hotel/venue security or local law enforcement, provide escorts, or otherwise assist those experiencing harassment to feel safe for the duration of the conference. We value your attendance and want to create a safe space for participants.

Vendors, Contractors and Third Parties

The convention’s policies on discrimination, harassment, and sexual harassment apply to the conduct of vendors, contractors and third parties. If a member of the GridLOCK community believes that he or she has been subjected to conduct by a vendor, contractor or third party that violates these policies, the community member should contact a staff member, volunteer, or another appropriate authority. GridLOCK will respond as appropriate, given the nature of its relationship to the vendor, contractor or third party.

This policy is based on Geek Feminism’s harassment policy template.
